Hi all,
I want to use the EMMC as USB storage space.After connecting to the computer and successfully formatting, I found that the file transfer speed is very slow (write speed is 1-2 Mb/s, read speed is 2-6 Mb/s).
After enabling DMA, the speed still hasn't improved.
And I referred to an example(https://github.com/STMicroelectronics/x-cube-azrtos-h7/blob/main/Projects/STM32H735G-DK/Applications/USBX/Ux_Device_MSC) and switched the read/write interface to DMA(BSP_MMC_WriteBlocks_DMA,BSP_MMC_ReadBlocks_DMA), but the enumeration failed. Is this due to differences in the chip series or incorrect configuration?
Aside from this, are there any other methods to improve the speed?
The attached file is my project.
